CABLE-CLAMP.

Specification of Letters Patent.

' Patented Mar. 25, 1919.

Application filed October 15, 1918. Serial No. 258,158.

To all whom it may concern:

Be it known that I, JAMEs KELLEY, a citizen of the United States,residing at Clarkia, in the county of Shoshone and State of Idaho, haveinvented certain new and useful Improvements in Cable-Clamps, of whichthe following is a specification.

The present invention relates to improvements in cable clamps adaptedespecially for use in securing loops at the ends of draft cables. Thepresent device is particularly adapted for what are commonly termedchoke-lines, which are used by operators in getting out timber, such assaw logs, and these choke-lines are employed for the purpose of draggingor lifting the logs to the cars in loading. Each choke-line is providedwith loops at its ends, and the breaks, which frequently occur, aremainly at the splice joint of these loops, which are usually made fromthe cable itself. Inasmuch as the steel cables are expensive,considerable loss is incurred when the cable becomes worthless becauseof the breaking therefrom of the loop, because the remainder of thecable is of insuflicient length to permit reforming a loop at the end ofthe cable, and in many instances the cable length is a total oss.

The object of the present invention is to provide a clamping device bymeans of which loops of separate material, as for in stance cables fromwhich the integral loops have been broken, may be firmly and securelyattached to the cable length after the integral loop has been brokentherefrom, thus saving the cost of the cable, and also providing anefficient device for clamping the cable portions to form the loop.

In the accompanying drawings one complete example of the physicalembodiment of the invention is illustrated, constructed and arrangedaccording to the best mode so far devised, for the practical applicationof the principles of the invention.

Figure 1 is a view showing a choke-line as used in logging operations, aloop being shown in the body of the steel cable, which fits about thelog.

Fig. 2 is an enlarged plan view showing the end of a cable with the loopbroken and the clamp in position.

Fig. 3 is a perspective view, looking at the inner face of one of theclamp plates that form the clamping device.

Fig. 4 is a transverse vertical sectional View at line 4, 4, of Fig. 3.

In order that the preferred form of the invention may be readilyunderstood I have illustrated a complete choke-line comprising thesteel-cable 1, the end loops 2, and 3, and formed with a body loop ortwist 4 in dicating the manner of attaching to a log, while 5 is aslidable hook on the cable for making fast the cable in usual manner.

The essential part of the invention resides in the means of attachingthe loops 2 and 3 to the cable 1 and as the clamping devices areduplicates, a description of one device will sufiice for both.

In forming the loop 2 a suitable piece of steel cable is employed, ofthe proper size, and its ends are preferably frayed or its strandsseparated and the end flattened, as indicated in dotted lines Fig. 2.The end of the cable to which the loop is to be attached is also frayedby having its strands separated and the end flattened out, and thenametal band 6 is fastened, by hammering, about the three ends to holdthem securely together in a flattened position.

The cable and loop are now ready to receive the clamping platesindicated as a whole by the numerals 7 and 8, which plates areduplicates and provided with alined openings 9, 9, and side flanges 10,10, there being a recess 11 in each plate at that portion which becomesthe outer end of the plate. These recesses are formed in the flanges,and together provide an opening for the ends of the loop. At the innerend of the clamp plates they are formed with semicylindrical sleeves 12which project beyond the outline of the plates, which, in general shaperesemble a heart. The two plates are of course complementary and whenplaced together as indicated, they form a casing for inclosing the threeends of the cable and loop, and by means of rivets 13 passed through thealined holes 9 the plates are securely clamped over the cable and loop,with the sleeve portions 10 embracing the cable, and the opening formedby the recesses 10 accommodating the loop ends as they converge in thecasing. Upon their inner faces, each clamp plate is provided with aseries of parallel rows of teeth, the teeth of the central row 14 bitingin one direction and the teeth of the two outer rows 15 and 16 biting inthe opposite direction, so that when the two plates are brought intoclamped relation to the frayed ends of the cable and loop these teethbite into the strands of the three ends to hold them against strainsthat would tend to pull them out of the casing. To further hold theparts together molten metal, as Babbitt metal is poured into the casingformed by the complementary plates, and as the metal penetrates into thecavities and spaces around the strands and teeth, it will readily beseen that, after the metal has hardened, the three ends of the cable andloop are firmly and rigidly set and fastened Within the two clamp platesto form an efficient fastening or splice for the loop.

Claims:

1. The combination with the cable end and loop ends frayed, and a bandencircling these ends, of a: pair of complementary clamp plates havingflanges to form an in closing casing for the three ends, and rivetspassed through the plates, for clamping the ends as described.

2. The combination with a cable and loop ends, of a pair ofcomplementary plates each provided With parallel rows of biting teethand the teeth in the rows biting in opposite directions, said plateshaving flanges to constitute an inclosing casing, rivets securing theplates together, and cast metal within the casing embedding the cableand loop ends and said biting teeth.

In testimony whereof I afiix In signature.
